Route Email Receipts to Monarch

A connected-inbox workflow for Monarch receipt imports—not a native Monarch API integration

Monarch accepts receipt emails at receipts@my.monarch.com. Expensent helps you find, review, and route the right inbox receipts to that address from your connected mailbox. Monarch then owns receipt import, parsing, matching, splitting, categories, and notifications.

This is a forwarding workflow through Monarch's documented receipt address. Expensent does not connect to a Monarch account through an API, and it does not bypass Gmail or Monarch verification controls.

The Inbox-to-Monarch Gap

Monarch provides the receipt destination, but finding and sending every inbox receipt still creates upstream work:

•Receipt emails accumulate across vendors and months
•Gmail native automatic forwarding cannot be enabled until the destination mailbox confirms Google’s verification link
•A forwarded message can fail at intake or arrive without matching a transaction
•Historical receipts need discovery and review before they can be routed safely

The Expensent Workflow

Connect Gmail or Outlook to Expensent with OAuth, review likely receipt emails, and send selected messages from the connected mailbox to receipts@my.monarch.com. For repeat patterns you trust, create an email-pattern and subject-pattern rule.

Inbox discovery: Surface likely receipt and invoice emails, including historical items found during a scan
Review before routing: Check likely receipts and exceptions before sending them downstream
Connected-mailbox sending: Send from the authorized mailbox instead of configuring Gmail’s forwarding destination
Pattern controls: Create repeat rules from a reviewed sender and subject pattern
Clear handoff: Monarch remains responsible for importing, matching, splitting, categorizing, and notifying

What Monarch Does After a Receipt Arrives

Monarch's current receipt-import documentation says verified senders can email one receipt at a time to receipts@my.monarch.com. After import, Monarch attempts to match the receipt to an eligible posted transaction.

•The Monarch account email and household-member emails are documented as already verified; other sender addresses require a Monarch verification code
•Monarch currently documents JPG, PNG, WEBP, HEIC, HEIF, and PDF as native email attachments, plus body-only email receipts
•Monarch currently documents 10 MB per attachment and 30 MB per email, with one forwarded email treated as one receipt
•Pending transactions are not eligible for matching until they post
•Monarch handles receipt records, parsing, matching, Autosplit behavior, categories, notes, tags, and notifications

Attachment boundary: Monarch’s native format list is broader than the PDF, JPG, and PNG attachments Expensent currently supports. Do not assume every Monarch-native format can travel through every Expensent path.

How to Set Up the Workflow

Verify the sending mailbox in Monarch

Use the Monarch account email, a household-member email, or add the connected mailbox under Transactions > Receipts > Settings and complete Monarch’s six-digit sender verification.

Connect the mailbox to Expensent

Authorize the Gmail or Outlook inbox with OAuth, then set receipts@my.monarch.com as the software destination.

Review and send a test receipt

Choose one clear receipt, send it from the connected mailbox, and confirm it appears in Monarch’s Receipts tab before creating repeat rules.

Add bounded rules for proven patterns

Create rules only for stable email and subject patterns. Keep portal links, unsupported files, bundled receipts, and ambiguous messages in review.

Monarch Receipt Workflow FAQ

Is Expensent a native Monarch API integration?

No. Expensent uses Monarch’s documented receipt email workflow. It helps discover, review, and route inbox receipts to receipts@my.monarch.com; Monarch remains the receipt-processing and matching system.

Does this bypass Gmail forwarding verification?

No. Expensent sends an authorized outbound message from the connected mailbox rather than configuring Gmail’s automatic-forwarding destination. Google’s destination-verification step is not part of that sending path, but no security check is bypassed.

Do I still need to verify my email address in Monarch?

Yes, unless Monarch already treats the address as verified because it is the account email or a household-member email. Any other connected sending mailbox must complete Monarch’s separate sender-verification flow.

What files can Expensent send to Monarch?

Expensent currently supports PDF, JPG, and PNG attachments. Monarch documents additional native formats, but that does not make those formats universally available through Expensent. The optional body-as-proof preference controls whether detected body-proof items are shown and whether newly created rules require attachments; it does not change manual-forwarding eligibility or rewrite existing rules.

Will every forwarded receipt match automatically?

No. Monarch attempts matching after import using transaction and receipt details, and pending transactions are not eligible until posted. Review unmatched receipts in Monarch and use its manual matching controls when needed.

Can Expensent catch up old Monarch receipts?

Expensent can help surface historical receipt emails during inbox scanning so you can review and route eligible items. Gmail filters only apply to new arrivals; Monarch still decides whether each routed receipt imports and matches.

Get Started

How Automatic Invoice Forwarding Works

Expensent connects to your email inbox and uses AI to surface likely invoice and receipt emails. Each document is grouped by what needs to happen next: ready to forward with a PDF attachment, needs a download from the vendor portal, needs your review, or not an invoice. You review the queue and decide what happens next.

One-Click Forwarding and Auto-Forwarding Rules

Forward a selected invoice to your accounting software with one click. Or create an auto-forwarding rule from a reviewed email and subject pattern so future arrivals can follow the same route. Rules are created from existing emails with one click.

Works With Many Accounting Platforms

Forward receipts to QuickBooks Online, Xero, Expensify, FreshBooks, Ramp, Brex, BILL, Dext, SAP Concur, Wave, Zoho Expense, Hubdoc, Emburse, Pleo, Rydoo, Divvy, Revolut Business, or another reviewed forwarding destination. Each platform has its own rules for how receipts are received, processed, extracted, or matched.

Privacy and Security

Expensent uses OAuth authentication to connect to your inbox — your password is never shared. AI prefilters on email metadata only, so personal emails are filtered out without their content ever being read. You control which invoices are forwarded and where they go.
